Notes:

1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up

column (wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input,

else the configuration is floating interrupt input.

2. In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to VDD

are not implemented). See See “I/O PORTS” on page 44. and Section 12.8 I/O PORT PIN CHARACTER-

ISTICS for more details.

3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, an RC oscillator, or an external source to

the on-chip oscillator; see Section 1 INTRODUCTION and Section 12.5 CLOCK AND TIMING CHARAC-

TERISTICS for more details.

4. On the chip, each I/O port has 8 pads. Pads that are not bonded to external pins are in input pull-up con-

figuration after reset. The configuration of these pads must be kept at reset state to avoid added current

consumption.
